4.2.8 Procedure of payment of Earnest Money and Bid Document Fee through Axis Bank Gateway :

The bidder would be able to access the payment gateway from the Vendor login page of the MSTC ecommerce site (www.mstcecommerce.com → e-Procurement → PSU/Govt. depts. → Kolkata Port Trust) under the icon “HDC EMD/Tender Fee Payment”. Clicking this icon will take the bidders to the Axis Bank Gateway. Alternatively, the bidder can also access the gateway by from Axis Bank Easy Pay website (https://easypay.axisbank.co.in → Others → Haldia Dock Complex).

The bidder will be required to mention the bidder’s ID (the ID used by the bidder for logging in the MSTC website) and Bid ID (E-Tender No. of the tender against which the bidder intends to submit bid) and then click ‘VALIDATE’.

A webpage will populate, where the bidder will be required to select “Earnest Money” OR “Bid Document Fee”, then indicate his Mobile Number and the CAPTCHA displayed in the webpage.

Depending on the selection, another webpage will come up. In case of selection of Earnest Money (EM), the bidder will be required to select

the option of With or Without Bank Guarantee. In case of the instant tender, where there is no option to pay the EM through Bank Guarantee (BG), the bidders should select the option ‘Without’.

The bidder will be required to mention their Bank Account Number, IFSC of


12

their Bank and the name of the account, insert the CAPTCHA mentioned in the webpage and then ‘SUBMIT’. In case of Bid Document Fee payment, Bank Account Number would not be required. An URN Number will be generated. Bidders should keep note of this URN Number for all future reference.

Another webpage will come up and the bidder will have the option to select payment methods from – (i) Internet Banking and (ii) NEFT/RTGS, after agreeing with the terms and conditions, by clicking the dialogue box appearing in the webpage.

In case of selection of Internet Banking, the bidder will be required to select any Bank of their choice and depending on the selection, the bidder will then be guided to the webpage of the respective Bank. After validating the payment in the respective Bank, the system will return to the Axis Bank Payment Gateway.

In case of selection of RTGS/NEFT, the webpage will generate a payment advice. The Bank Account Number, IFSC of the Bank, name of the payee, i.e., Haldia Dock Complex, and the amount to be paid will be indicated in the said payment advice. The bidder will also get an SMS and e-mail detailing the same. The bidder will be required to mention the same correctly in the Bank Challan, which is required to be filled up for payment by RTGS/NEFT in the Bank from where they intend to make the payment. The bidders should note that Bank a/c number of HDC, mentioned in the Payment Advice, will change for each and every transaction and hence, for each and every payment, the entire process from the beginning will have to be followed for generation of a URN Number.

For payment of Bid Document Fee, identical process is to be followed. The bidders will be able to know the status of their payment, by using the

‘Enquire URN’ facility, by mentioning the URN Number in the Axis Bank login page. Until such time the payment is credited to HDC’s a/c, the system will show the status as ‘Pending’.

The bidders should note that until such time the status remains ‘Pending’, the payment is not made to HDC and mere generation of URN Number will not signify payment of EM or Bid Document Fee. Hence, if the status remains ‘Pending’ after some time of submitting the RTGS/NEFT payment request at their Bank, then the bidders should contact their Bank to enquire about the status of RTGS/NEFT request.

In case of any problem relating to use of the payment gateway, the bidders should contact the tender inviting authority, whose phone number and e-mail address are mentioned in the e-Tender.
